THE BENCHMARK SCHEME
Benchmark places responsibilities on both manufacturers and installers. The purpose is to ensure that customers are
provided with the correct equipment for their needs, that it is installed, commissioned and serviced in accordance with
the manufacturer's instructions by competent persons and that it meets the requirements of the appropriate Building
Regulations and relevant electrical qualifications. The Benchmark Checklist can be used to demonstrate compliance with
Building Regulations and should be provided to the customer for future reference. Installers are required to carry out
installation, commissioning and servicing work in accordance with the Benchmark Code of Practice which is available
from the Heating and Hotwater Industry Council who manage and promote the Scheme. Visit www.centralheating.co.uk
